Returning negative numbers or other codes is not -permissible since coupled CPU idle was merged. - -At least some of the mvebu_v7_cpu_suspend() implementations return the -value from cpu_suspend(), which returns zero if the CPU vectors back -into the kernel via cpu_resume() (the success case), or the non-zero -return value of the suspend actor, or one (failure cases). - -We do not want to be returning the failure case value back to CPU idle -as that indicates that we successfully entered one of the deeper idle -states. Always return zero instead, indicating that we slept for the -shortest amount of time. - -Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> ---- - drivers/cpuidle/cpuidle-mvebu-v7.c | 6 +++++- - 1 file changed, 5 insertions(+), 1 deletion(-) - -diff --git a/drivers/cpuidle/cpuidle-mvebu-v7.c b/drivers/cpuidle/cpuidle-mvebu-v7.c -index 01a856971f05..18ded9e7cb34 100644 ---- a/drivers/cpuidle/cpuidle-mvebu-v7.c -+++ b/drivers/cpuidle/cpuidle-mvebu-v7.c -@@ -39,8 +39,12 @@ static int mvebu_v7_enter_idle(struct cpuidle_device *dev, - ret = mvebu_v7_cpu_suspend(deepidle); - cpu_pm_exit(); - -+ /* -+ * If we failed to enter the desired state, indicate that we -+ * slept lightly. -+ */ - if (ret) -- return ret; -+ return 0; - - return index; - } --- -2.37.2 - |
